Abstract
An actuator for an injection molding tool includes a housing, a plunger and a slide member. The housing includes an aperture extending therethrough and a first recess extending through an open end of the aperture. The plunger is slidably received in the aperture and is movable therein relative to the housing between first and second positions. The plunger may include a second recess formed therein that cooperates with the first recess to define a cavity when the plunger is in the first position. The slide member slidably engages the plunger for movement relative to the plunger between an extended position in which the slide member extends into the cavity and a retracted position in which the slide member is retracted out of the cavity.
Claims20
An actuator for an injection molding tool, the actuator comprising:
- a housing including an aperture extending therethrough, the aperture including a first recess extending through an open end of the aperture;
- a plunger slidably received in the aperture and movable therein relative to the housing between first and second positions, the plunger including a second recess formed therein that cooperates with the first recess to define a cavity when the plunger is in the first position;
- and
- a slide member slidably engaging the plunger for movement with the plunger between an extended position in which the slide member extends into the cavity and a retracted position in which the slide member is retracted out of the cavity.
An injection molding tool comprising:
- a first mold block;
- a second mold block cooperating with the first mold block to define a first cavity therebetween;
- and
- an actuator supported by one of the first and second mold blocks, the actuator including a housing, a plunger and a slide member, the plunger being movable within the housing and cooperating with the housing to define a second cavity therebetween that is in communication with the first cavity, the slide member movable with to the plunger between an extended position in which a portion of the slide member is received in the second cavity and a retracted position in which the portion of the slide member is retracted from the second cavity.
